Usage

showdist(A) displays the distribution of a DArray A.

showfield(A, field, inds...; axis = 0) fetchs and displays the field of a DArray A of a self-defined datatype in the range of inds. The default range is all if no inds is provided. If the field is vectorial, set axis to display the component in the axis-th direction.

Examples:

julia> using Distributed

julia> addprocs(4)
4-element Array{Int64,1}:
 2
 3
 4
 5

julia> @everywhere using DistributedArrays

julia> @everywhere using DUtils

julia> b = [@spawnat pid [pid,pid*10] for pid in workers()]
4-element Array{Future,1}:
 Future(2, 1, 14, nothing)
 Future(3, 1, 15, nothing)
 Future(4, 1, 16, nothing)
 Future(5, 1, 17, nothing)

julia> a = DArray(b)
8-element DArray{Int64,1,Array{Int64,1}}:
  2

julia> showdist(a)
